SPECIFICATION forming part of Letters Patent No. 452,057, dated May 12, 1891.

Application filed July 10,1890. Serial No, 358,349. (No model.)

To all whom it may concern.-

Be it known that 1, ADOLPH O. ALBRIGHT, of St. Louis, Missouri, have made a new and useful Improvement in Typeriting-Machine Attachments, of which the following is a full, clear, and exact description.

The invention is an improved means for shifting the paper-cylinder on the Remington type writing machine, substantially as is hereinafter described and claimed, aided by the annexed drawings, making part of this specification, in which Figure 1 is a side elevation of a type-writing machine having the improvement. Only those parts of the machine which are essential to an understanding of the improvement are shown, and a portion of the frame-work is broken away to exhibit the construction beyond; Fig. 2, a front elevation of the same, portions of the uprights of the frame being broken away to exhibit the construction beyond; Fig. 3, a vertical section upon the line 3 3 of Fig. 2, and Fig. 4 a vertical section on the line 4. at of Fig. 2.

The same letters of reference denote the same parts.

The type-writer A is of the usual description, saving as itmay be modified or supplemented by the present improvement.

B represents the paper-cylinder, and O 0' represent the customary bellcrank levers upon the shaft D for shifting the paper-cylinder. The movement of the lever O isindicated by the broken lines in Fig. 1.

E represents a key-lever arranged at the left-hand side of the key-board F. The keylever is journaled at its upper end 6 upon a bearing Gr, so that the key-lever can be vibrated vertically, as indicated by the broken lines in Fig. 1. The bearing G is a rod held in the uprights a a of the machine.

H represents a connecting-rod leadin g from the arm 0 of the bell-crank O and connecting with the key-lever E at a point thereon between its ends, substantially as shown. The connecting-rod, by means of the swivel h, is adapted to be lengthened or shortened to a limited extent to enable the lever and keylever to be properly connected. By depressing the forward end. e of the key-lever E the lever O is caused to turn, as indicated, and

the paper-cylinder thereby shifted backward in the machine, as indicated by the broken lines in Fig. 1. On releasing the key-lever E the usual means (not shown) operate to restore the parts named to their original respective positions.

The key-lever at its point of connection with the bearing G is extended laterally for several purposes. By so extending it the keylever is less liable to swing sidewise in its operation, and to this end it is desirable in practice to extend the lever end 6, say, an inch or two, upon the bearing G. Further, it is desirable to be able to shift the paper-cylinder by means of a key-lever at the righthand side of the key-board as well as by the key-lever atthe left-hand side thereof, and to this end the lever end 6 of the key E is extended along the bearing G across the machine, and at the right-hand side thereof is shaped to form, or is provided with, a key-lever E, which is substantially similar in construction and operation, and so that whichever key-leverE or E is struck the paper-cylinder is operated. Further, I take advantage of that portion of the described construction which is between the key-lever E by shaping it to form or providing it with a pencil-holder I, substantially as shown. This pencil-holder may also be utilized as akey-lever to operate the paper-cylinder in a manner analogous to that employed in operating the key-lever E E, and the holder I may be extended as a lever forward more or less above the keyboard.

Fig. 4. illustrates a mode of securing the key-lever E upon the bearing G. A screw e passes through the forks e e of the key end e. Other modes, if necessary, may be used.

It is not essential that the key end e, when it is widened, as described, to support the pencil-holder or to connect with the key E, be jointed continuously upon the bearing G from one side of the key-board to the opposite side thereof. The direct connection with the bearing may be omitted at various points.

I claim 1. The combination of the bell-crank lever adapted to actuate the paper-cylinder, the connecting-rod, and the right and left hand key-levers, one key-lever having a lateral extension at its pivotal point, to which is connected the other key-lever, substantially as set forth.

2. The combination of the bell orank lever adapted to actuate the paper-cylinder the' connecting-rod, the bearing-rod, and the keylevers, one having a lateral extension resting upon said bearing-rod, and to which is connected the other key-lever. the fulcrum ends of said levers having a U shape, through one of which is inserted a screw-bolt holding-it upon said bearing-rod, substantially as set 20 forth.

\Vitness my hand this 7th of July, 1890.
